tween each escapement and the keyboard. for talnng up all overthrow orexcess motion which may be provided to compensate for Wear of the camroller and the parts between it and the escapement, certainty inoperation of the escapements being thereby insured.

To these and other ends, the invention consists lncertain improvements,and comblnations and arrangements of parts. all as will be hereinaftermore fully described, the novel features being: pointed out particularlyin the claims at the end of the specification. In the accompanying'drawing:Figure 1 .is a perspective view of a section of the mechanismof a linotype machine which controls the delivery of matrices from themagazine, the escapement mechanism shown 'tirerein embodying the presentinvention; Fig. 2 represents a vertical section of the structure shownin Fig. 1, the parts being in normal. or inactive condition; Fig. 3 is aview similar .to Fig. 2 showing one of the escapements actuated torelease and cause de livery of a matrix from its respective channel ofthe magazine; Fig. 4 is a perspective view of one of the escapementmembers and its mounting. Fig. 5 is a view showing dia- '-jgrammatically the converging, matrix channels of the magazine and thecorresponding convergence or angularity of the cscapement grooves in theescapement bar.

Similar arts are designated by the same reference ciaracters in theseveral views.

Heretofore in machines of this character,

the escapements, which control the delivery Ofiillfi matrices from themagazine, have been pivoted on a pin operatin; in a hole in theescapement, the pin forming the axis of oscillation of the escapementpoints. Owing to the fact that the channels of the magazine containa-large number of matrices which are fed by gravity to the rcsl'icctivoescapeinents, considerable wear between each cscapement and its pivotpin has resulted in previous constructions due to the repeated.checku'ig of the line of stored matrices by the escapement during thedelivery of the matrices, and experience has shown that the wear soproduced results 'l'rcqucntlv in faulty delivery of the matrices,occasioniug numerous delays in the operation of the ma- The presentinvention provides a construction which obviates the defectsandobgection incident to the escapemcnt mecha- -more readily as comparedwith previous 1 n constructions, the escapement member. in the preferredembodiment of the invention be- 7 mg in one pleoe, thus reducingmaterially the number of'partsand connections employed, and theescapement is so mounted as to mmlmlzef wear and to 2118111684111correct working relations of the parts." The preferred embodiment ofthe' invention is shown in the accompanying drawing and will behereinafter described in. detail, but it is to;.be understood that theinvention is not restricted to the particular construction h shown asequivalent constructions may be usedwithin the scope of the claims.

In the present instance,the improvements are shown in connection withthe well known linotype machine, the keyboard mechanism of whichembodiesthe usual key levers 1 cooperating with the vertically movablekey bars 2 and the atter cooperating with the bell-crank levers 8 whichare pivoted at 4 on the cam frame}5,'these bellcrank levers controllingthe cam yokes 6 in the usual manner, these cam yokes being pivoted at 7and having cams 8 journaled thereon, the cams being arranged tocooperate with the continuously revolving cam rollers 9. Each cam -isnormally held in inoperative position by a pin 10 thereon whichoooperates with a toothed bar 11, lowering of the cam yoke serving intheusual manner to set the cam 8 in coiiperative relation with therespective cam roller 9, and rotation of the latter serves to elevatethe cam yoke and thereby operate the respective'escapement to deliver amatrix from the corres )onding channel .of the magazine. In th "presentembodiment of the invention, means is interposed between the keyboardmechanism and the escapements to take up or compen sate for overthrow orexcess motion of the cam yoke, such excess motion being preferablyprovided in order to allow for wear of the cam roller and the associatedparts. In the present instance, the escapements are actuated by a set ofvertically movable reeds 12 which are guided by the bars 13, each reedresting on and coi perating with an actuator which is operated by acorresponding cam yoke. In the preferred form, each actuator embodies aplunger 14 which is fitted to operate vertically in the cam frame 5 andthe upper end of this plunger forms a head which cooperates with thebottom of its respective reed. The plunger is formed with a chamber 15and an auxiliary plunger 10 is provided which is capable of'moving-axially in the chamber of the plunger 11 and is permitted alimited movement with respect to the plunges 14 by the transverse pin 17which operates within gaged by the respective cam yoke when the same rses and the spring 19 then serves to transmit the .movemcntof theauxiliary plunger 16 to the plunger 14 and the latter will actuate itsrespective reed and the reed in turn will operate its respectiveescapement to release and cause delivery of a matrix from thecorresponding channel of the magazine. When, however, the cam yoke as anexcess motion, the plungers 14 and 16 will move in unison until theescapemerit has reached the limit-of its movement, and further movementimparted to the plunger 16 by the cam yoke causes compression .of

the spring while the plunger 14: remains at rest, the springconstituting a yielding or compensating connection between the cam yokeand the reed.

The magazine 20 is shown in'the present instance as provided with theusual channels 21 to contain the matrices, the matrices bein'g fed tothe es'capements and to the mouth of the magazine by gravity. Theimproved escapement mechanism provided by the present invention embodiesa set of escapements corresponding in number and position to themagazine channels, each escapement in the preferred form of theinvention embodying a member 22 which is of segmental'form and made inone piece. Each escapement member in the present instance issubstantially semi-circular in form and 1t has a concentric innerbearing edge 23, the

ends of the memberv forming pallets orstops 21 and 25 to coiiperate withthe ears on the matrices and thereby control the movements thereoftoward the mouth of the magazine.

finch escapement member is also provided secured by screws 30 to theunderside of the magazine, and this bar is formed with a number ofconcentric segmental grooves which correspond in number. and arrange:ment to the es't'apemc'nt members, these sege mental grooves in the barreceiving the .different escapement members and causing the same tooscillate about a glvenaxis andpreventing lateral displacement thereof.cording to the present invent1on, the axis of oscillation of theescapement members is located preferably on a line betweenthe pallets ormatrix-engaging ends thereof and is within the channel portion of thelonger drical bearing for the respective escapement',

the axis of which bearing is at a rightangle to the plane of therespective escapement and the corresponding matrix. channel of themagazine, this right angular relation between the escapements and theaxes of their bearings being maintained across the width of themagazine, notwithstanding the fact that the matrix. channels in themagazine are convergent, asshown in Fig. 5, and the escapements bear acorresponding convergent relation. The upper side of the bar 29 ivhichin the present instance forms a portion of the bottom of the magazine isformed with grooves or channels 32 which constitute continuations of thechannels or grooves 21 in the bottom of the magazine. Each escapement isprovided with 1 spring 33 which is supported by a block 3 and acts onthe lug or projection 26 of the escapement to counteract therespective-reed and to restore the escapement to normal position aftereach actuation thereof. A guard or cover plate 35 is also provided whichis secured to the under side of the magazine, it forming a housing forthe springs 33 to protect the same and it has a lip or extension 36which bears on the under sides of the escape'ment members to retain themin their res ective bearings provided by the bar :29.

he operation of the mechanism shown may be briefly described as follows:\l"hen the key bar 2 is elevated by manipulation of its respective keylever 1, the cam yoke 6 will be lowered, permitting the'correspondingcam 8 to be rotated by reason of its engagement with the continuouslyrevolving cam roller 9., the cam yoke being thereby ele vated and theupward movement of the cam yoke will carry it, into engagement with theauxiliary plunger l iand cmitinued rising movement it the ram yoke willcause the plunger it and its correspmding reed to be elevated throughthe medium of the spring 19 which is operated by the plunger 16. Thereed will act on the actuating projection 27 of its correspondingescapement, causing the same to move from the position shown in Fig. 2into the position shown in Fig. 3, the projection 25 on the escapementthereby reasing the lowermost matrix in the re spective magazine channeland the projec' arrestingof the movement of the plunger 14 and itsrespective reed. When the keyboard mechanism has returned to normalposition, the reed and its corresponding plunger 1% will descend and theescapement will be restored to its normal orinitial position by itsrespective spring.
